**Update**
Thank you all for the advice and consultation. I spent a bit of time arguing on the phone with the solar company. The sales person was not fully educated on solar and kept disagreeing that this would solve the issue but they agreed to install the 2 inverters per the contract. The replacement of the 10k inverter with 2 7600 watt inverters was completed yesterday. Today my system output 12.3kw at the peak around noon.
To avoid mistakes like mine, understanding the initial design is important, but monitoring the installation and validating the right equipment is being installed is critical.
For those who asked about this being a single string as pictured in the monitoring app. The monitoring app shows it as one string, but there are actually 3 strings wired. The app shows a single string for an inverter no matter how many strings actually exist. With the 2 inverters it now shows 2 strings. There are still 3 strings, 2 connected to the lead inverter and 1 connected to the secondary inverter.
** Thank you again for the input, knowledge and education.**
Just had solar installed at my house a few months ago by a local company. I have noticed something odd in the monitoring. Each day around 10 am I hit production of 9.96 kw. It stays there for a few hours and then starts declining as the sun goes down. I thought with a 12.8 kw system I would see higher production during mid day. I called the solar company and they said this was completely normal behavior for a 12.8 kw system.
To me (untrained but logical thought process) there should be some variation from 10 to noon as the sun rises and a gradual decline in the afternoon. Constant unvaried output of 9.96 kw from 10 am to sometime in the afternoon seems to be a limitation of the system somewhere. I thought likely the inverter is undersized but the solar company swears this is normal behavior. To me the graph should peak as the sun is highest overhead and gradually decline. (adjusting for angle and orientation)
Am I crazy here or missing something? System is 32 of the 400 watt q-cell panels with Solar Edge SE 100000h inverter grid tied.
